, 1 Application tiled October 20, 1913. Serial No. 796,192.

Toall lwhom it mag/,concern n 1 `Be it known that I, WILLIAM E. TEKLEN-i' BURG, citizen of the United States, residing at Cincinnati, in thecounty of Hamilton and State of Ohio,"have invented certain new anduseful'lmprovements in Lubricanty Pumping Mechanism, `of which thefollowis a specification.

y invention relates to improvements in lubricant pumping mechanism.

kOne of its objects is to provide an 17mproved pump, 1n which theoperative parts f y are all housed and (protected from injuryk f dirtwhilethea j l5 ustments to operative parts and access to valves may bereadily made and had from the exterior.` `Another object is `,to provideimproved means, whereby the ypump may be selectively "Another object isto provide an improved ".fassembly of casing, operative parts and *yvalves, whereby the machine work required reduced to `a in quantlty andsingplicity in nature.k

y invention also comprises certain detals of form, combination, andarrangekk', improved mechanism on line a-a of Fig. 2.,

lment, all of which will be fully set forth in the description of theaccompanying draw-` ings, in which: y n

andy adjusting .mechanism detached. Fig. 4

j iis a sectional detailH illustrating the ratchet driving mechanism,online d-d of Fig. 1.

` Fig.-5 isa rear end yview partly in section on line 0 0 of Fig. 6.Fig. 6 is a frontend elevation. Fig. 7 is a perspective view of thestrainer cap and latch detached.

The accompanying drawings representthe ji preferred embodiment of myinvention, in

which A represents a rectangular metal casing, in which the operativeparts are mounted and housed. The operative parts and valves are soarranged with reference to the casing, that throughholes may be bored inthe casing and similarly tapped if required to provide the requisiteports and passages, thereby reducing the `work requisite on the `casingto a minimum.

B represents the main or operating shaft which is journaled at one endin a blind journal boX 2, tapped into the rear end of the casing. Theopposite end of shaft B is journaled in a blind recess or bearing in thesleeve 3, which in turn is journaled in a sleeve bearing 4, tapped intothe front end of the casing and provided with a packing gland 5. Thesleeve 3 outside of the casing has a crank arm 6 keyed thereto and acrank arm 7 loosely journaled thereon. The crank arm 7 is attached bymeans of an extension rod 8 to some reciprocating part of the mechanismto be lubricated to cause the crank arm 7 to oscillate in unison withthe movements of said mechanism. The crank arm 6 has a handle 9, bymeans of which it maybe turned by hand to give an initial charge of oilto the mechanism, or for other purpose, and is also provided with aspring actuated dog 9 or stud to engage a recess 10 in the crank arm 7to lock said crank arms together and cause them to move in unison.`

`Said stud is disengaged from the crank arm 7 when it is desired to turncrank arm 6 by hand by pulling outwardly on the handle 9.

At the inner end of the sleeve 3, is a crank arm 11 armed with a pawl 12which engages the teeth of a ratchet wheel 14C keyed upon the sha-ft B.A pawl 15 pivotally attached to a bracket 16 on the inside of the casingalso engages the teeth of saidratchet wheel to prevent it being turnedin a reverse direction. Rigidly mounted upon the shaft B is a cam 17,which engages a yoke or strap 18, carried by a rod 19, which is therebyreciprocated endwise. The rod 19 is supported at one end in a recessbored in a boss 20 carried by the casing and at the opposite end in asleeve 21 threaded into a hole bored in the rear of the casing.

An arm 22 carried by the rod 19 is provided with a measuring pumpplunger 24, which reciprocates in a casing or sleeve 25, one end ofwhich is screwed from the 1nside of the casing into a threaded opening26 in the lower portion of front of casing A. The cylinder 27 of themeasuring pump is adjustably seated in the bore of the slee-ve 25, beingadjustable endwise therein from the exterior of the casing topredetermine or vary the amount of lubricant forced through the cylinder27 at each stroke of the plunger. The forward end of the cylinder 27seats in a recess in a sleeve 28 threaded into the forward end of the Ythreaded opening 26, said sleeve 28 being 2 Y Y v Lf... V.

provided with a threaded shaftm29 rotatably V held in place withreference to the sleeve 28 by a packing gland 30, and with its inner endthreaded into the forward end of the. cylinder 427 to adjust saidcylinder endwise'. A pin 3l sliding in a keyway in the sleeve 25prevents the cylinder 27 from rotating.

'lhe lubricant is fed through a strainer into the interior of thecasing' or reservoir A, from which it enters a port 33 in` Vthe sleeve25 and thence through `a port 34 in the side of the cylinder 27,' when`said port 34 is uncovered by retraction of the plunger 24. Thelubricant is expelled from the cylinder 27 b'y the forward movement ofthe plunger 24 'and escapes through a 1 port in the cylinder 27, and aslotin the inner end of the sleeve toa ballcheck 1falve 36 and thencethrough port 37 to another check kvalve 38, and thence'by tube'39 'to atransparent sight chamber 40. The'lcylinder 27 being normally submergedin oil avoids liability of air or gases enteringat the' ports 33 and3i4'to thereby alter* the v'volume of lubricant pumped throughthecylinder 27. The plunger 24 makes strokes vof uniform length, andwhen the 'plunger is :retracted the oil flows in'atport 34y as'soon' assaid port is uncovered by the plunger,

fand A(':ontin'ues `to flow iny until ythe plunger is `fully retracted.On `the forward stroke the j oil'is y'free to flow in `the oppositedirection from tliecylinder back 4to 'the casing A until the plungeragain covers fthe 'port 34, after which the oil remaining in cylinder 27is' forced'through the check valves-36 and 38,

y hence "when there is practically no vclearance between-the end of the`plunger'and inner end of the cylinder, the maximum volume of lubricantis being pumped, and correspondingly less volumes are pumped'as'the' vcylinder 4is adjusted endwise in its supports lto `increase the amountof clearance bet-Ween the cylinder head vandthe end ofthe plun- Lger,due to a portion of the oil in'the. cylinder not being expelledby theplunger.

-Froml'the chamber 40 the oil gravitates through a port 41 in thewallofthe casing A to a curved recess 42, -open on the outer face ofvsaidcasing at apoint 7 where the face of ysaid casing is dressed or faced. Apump cylinder 43 passes through openings 44fand 45 in opposite sides ofthecasing A,

- one of which openings 44 is concentric with the bore of the cylinder 43, and a packing ugland 50 preventsleakage from said cylinclaim is der.A cross bar 51 connects the plunger 49 with the're'ciprocatin'g rod 19outside of thek casing, thereby causing said plunger to reciprocate inunison with said rod 19.

Oil is passed from the curved Arecess 42 through ports 52 to two checkvalves 53k and .and thence into the cylinder 43 through a port 55 as theplunger 49 is retracted.

When the plunger 49 moves forward the oil in cylinder 43 is positivelyexpelled through lthe port 55 and past they check valves 56 `and A57 andthence through'a pipe' linel i to a point where it is tobe used as alubricant. `The valve chambers for vthe valves 5,3, 54, 'and'56,-`57,are formedin the enlarged head of the cylinder 43 andare accessible fromfthe'fexterior of the'casing. The valve 36'is also accessible'from'theexterior of the casl ing, and also the means for adjusting thev "cylinder 27.

A detachable'sheet metal cap -58 closes an `opening-at the top of -thecasing A and' permits access-'to theinterio'r of the casing ifrequired.-A stamped vsheet 4metal cap -59 closes `the 4opening to the `strainer-32 "a-'notch62 in the top rim of the strainer casing. `f

I -Inpracti'c'eone' ormore of the heretofore described measuring andpumping mechaynisiiis may be mounted side by sidein a single casing, or4in afcasing subdivided by partitions toV independently lubricatedifferent portions of a mechanism, measuring and feeding Vthe quantityof lubricantreand isv pivotal-ly'held in place by a'screw 60, and lockedin closeddposition by an integrally` formed spring latch member 61engaging f quired by each, of a single, or different y V`grades oflubricant.
